BOTTLE-RACK-ACTUATING DEVICE FOR BOTTLE-POLISHING MACHINES.

Application filed February 12, 1925. Serial No. 8,623.

This invention relates to bottle polishing machines of the type wherein a row of bottles is pressed against the periphery of a rapidly rotating polishing drum.

More particularly the invention relates to a bottle rack actuating device for polishing machines of this class.

One important object of the invention is to provide a novel arrangement of rocking to or oscillating bottle racks for a machine of this description.

A second important object of the invention is to provide an improved arrangement for shifting such bottle racks between their rocking and polishing position and their unloading and loading position.

A third important object of the invention is to provide an improved arrangement wherein the racks in moving between said positions are automatically tilted between horizontal and substantially vertical rocking positions.

With the above and other objects in View as will be hereinafter apparent, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings and specifically claimed.

In'the accompanying drawings like characters of reference indicate like parts in the several views, and:

Figure 1 is a side elevation of a polishing machine constructed in accordance withthis 3 invention one of the bottle racks being shown in polishing position and the other in loading position.

Figure 2 is a. plan view partly in section of such a machine.

. Figure 3 is a sectionon the line 3-3 of Figure 1.

Figure 4 is a detail part section to an enlarged scale showing one end of one of the bottle racks and its connections.

In the embodiment of the invention herein disclosed there is shown a polishing machine having a frame which is indicated in general at 10. On the upper part of this frame is mounted shaft 11 whereon is carried the polishing drum 12 which is provided with a suitable pan 13 and hood 1 L properly secured to the frame 10. This drum is formed from bristles, felt, cotton or flannel disks or any other suitable polishing material. At the rear of the machine is a jack shaft 15 on which is fixed a pulley 16 which is connected by a belt 17 with a similar pulley 18 fixed upon the shaft 11. The shaft 15 is driven from some suitable source of power such as is indicated by the belt 19. Projecting forwardly from the lower front part of the frame 10 is a pair of brackets 20 to which are pivoted the lower ends of the side members of a swinging frame 21 having at its upper end a bracket 22 wherethrough slides a rod 23. The rear end of this rod is held by a bracket 2 1 projecting up from the rear portion of the frame 10 and on the projecting front end of this rod is mounted a spring 25 one end of which bears against the front of the bracket 22 while its forward end is engaged by an adjusting hand wheel 26 screwed on the rod 23 and serving to regulate pressure urging the top of the frame 21 rearwardly.

On this swinging frameare mounted two stub shafts 27 wherco-n is fixed an oscillating or rocking frame 28 having a cross bar 29 provided with a bevelled face for purposes which will be hereinafter set forth. Secured to the under side of this cross bar are forwardly projecting supporting rails 30 and lateral guide bars 31. Extending forward from the frame 28 are the bearing brackets 32 wherein is journalled the shaft 33 having at each end a crank disk 34. Projecting radially from each of the disks 3% is a crank arm 35 which is connected by a link 36 with the respective end of a bottle rack or carrier 37. slidably on the rails 30 and is guided at its 9 ends by the guides 31. It will be seen that the rack is of L-shape and that a bottle placed on the rack rests with its base against the base of the Land its side against the stem or upright portion of said L.

Extending from the frame 28 at the ends of the cross bar 29 is a second pair of guide or supporting rails 38. Each of these rails first extends upwardly and forwardly at an acute angle to the frame 28 and then curves forwardly into a horizontal portion- Slidably mounted on the rails 38 is a second bottle rack 39 of exactly similar character to the rack 37 and, like it, connected to the disks 3% by links 10 and radial crank arms This bottle rack rests 41. To one of the disks is also connected an operating lever 42.

On the lower front portion of the frame is supported a shaft 43 on which is a pulley 44 connected by a belt 4.5 with a pulley 46 on the shaft 15. The shaft 43 is also provided with a pair of crank disks 47 which are connected by links or rods 48 with the frame 28 through arms 28 fixed to shaft 27.

In order to understand the operation of the device let it be supposed that the racks are as shown in Figure 1 and the shaft 15 to be revolving. Under these conditions it will be plain that the drum 12 will be revolving and the rack 39 will be oscillating in front of the drum so that the bottles carried by this rack will each have one side pressed against the drum and be moved to rock thereon. Meanwhile the rack 37 may be loaded if empty or unloaded and reloaded if full. t is to be understood that, if it is desired to polish more than one side or part of the bottles, such unloading and reloading may simply take the form of turning the bottles around. In any event, after the bottles on the rack 89 have been sufiiciently polished in their present position, the lever 42 is drawn forward. This will cause the rack 39 to tilt backward and glide up the rails 38 until it assumes the position shown in Figure 3. At the same time the rack 37, with its fresh load of bottles will move forward from the operator until it engages the bevel face of the cross bar 29. On arriving at this position further movement of the lever 4-2 will cause it to tilt upward as shown in Figure 3, thus bringing its botties into contact with the polishing drum. It is obvious that a reverse movement of the lever will restore the racks to their original positions.

There has thus been provided a simple and efficient device of the kind described and for the purpose specified.

It is obvious that minor chan es may be made in the form and construction of the invention without departing from the spirit thereof and accordingly it is not desire-d to confine the invention to the exact form here shown and described but it is desired to include all such as properly come within the scope claimed.

Having thus described the invention, what is claimed as new, is:

1. In a device of the kind described, a polishing drum, rack supporting rails extending from points adjacentthe drum, a bottle rack slidably mounted on said rails, a rack tilting device fixed in the path of said rack adjacentthe drum, an oscillating frame supporting said rails, and means to oscillate said frame. I

2. In a device of the kind described, a polishing drum, rack supporting rails extending away from said drum from points adjacent thereto, a bottle rack slidably mounted on said rails to move therealong toward and from the drum, a rack tilting bar extending above said rails adjacent said drum, means to reciprocate the rack on said rails, an oscillating frame supporting said rails, and means to oscillate said frame.

3. In a device of the kind described, a polishing drum, rack supporting rails extending away from said drum from points adjacent thereto, a bottle rack slidably mounted on said rails to move therealong toward and from the drum, a rack tilting bar extending above said rails adjacent said drum, a shaft extending in a direction transverse said rails in spaced relation to the drum, crank means carried by said shaft, links con necting sai-d crank means with the rack, means carried by the shaft for rocking the same, an oscillating frame supporting said rails, and means to oscillate said frame.

4. In a device of the kind described, a'

polishing drum, rack supporting rails extending away from said drum from points adjacent thereto, a bottle rack slidably mounted on said rails tomove therealong toward and from the drum, a rack tilting bar extending above said rails adjacent said drum, a shaft extending in a direction trans verse said rails in spaced relation to the drum, crank means carried by said shaft, links connecting said crank means with the rack, means carried by the shaft for rocking the same, other rails extending awa 1 from said drum from points adjacent the drum, a second bottle rack slidable on the last mentioned rails, said tilting bar being also in the path of the second rack, other crank means carried by said shaft, links connecting the last mentioned crank means with the second rack, said crank means being arranged to'cause the racks to move in opposite directions, an oscillating frame supporting said rails, and means to oscillate said frame.

In testimony whereof I aflix my signature.
